Abstract: PURPOSE:To raise specific power and thermal efficiency as well as to improve antiknocking properties, by installing a squishy area in position between a curved surface, being formed between ridgelines, and a cylinder hole, in a combustion chamber forming a cylinder head. CONSTITUTION:A first ridgeline 8 passes the center of a combustion chamber 6 of a cylinder head 2 and its length does not reach to a cylinder hole 4. Both second and third ridgelines 10 and 12 in parallel with the first ridgeline 8 are installed distributively at both sides. Each of spark plug setting holes 18 and 20 is made up in the central part of curved concave parts 14 and 16. A squishy area 30 is formed in space between curved surfaces 22, 24 and the cylinder hole 4 while another squishy area 32 is as well formed in space between curved surfaces 26, 28 and the cylinder hole 4.

Title: Microwave filter
Inventor: OKAMOTO NAOKI
IPC: H01P1/203
Filed: 1988-06-28
Abstract: PURPOSE:To change a line impedance without varying the stub width by providing an impedance line section varying the conductor pattern width of a middle part of a stub resonator and forming different impedance and reducing the reflection coefficient as the stub resonator. CONSTITUTION:A reflection coefficient in a signal frequency of the stub resonator is changed depending on the mount position of an intermediate stub 4 in the shape where the conductor part with different width is formed on the way of the stub length. For example, when the characteristic impedance Z4 of the intermediate stub 4 is 50OMEGA, the reflection coefficient is reduced more that the single line width resonance stub whose characteristic impedance is 141OMEGA in a range of the length l5 of the tip stub 5 being 5.0-6.5m/m. Thus, the transmission loss is reduced while keeping the line width wide. In the case of l5=5.5m/m, the reflection coefficient is 0.344 and the transmission loss equal to that of the single line width resonance stub whose line width is 100mum is suppressed.

Title: Bus hang-up avoiding method
Inventor: KUSABA YASUHIRO
IPC: G06F13/36
Filed: 1991-06-04
Abstract: PURPOSE:To avoid the hang-up state of an SCSI bus by transmitting an abort message to a target device when an initiator accepts invalid reselection from the target device. CONSTITUTION:In request to the invalid reselection, initiators 1 and 2 issue attention, request message out phase and accept the reselection and when the phase shown by target devices 3 and 4 is the message out phase, the initiators 1 and 2 output the abort message so as to inform it of the target devices 3 and 4 to stop processings. While responding to this information, the target devices 3 and 4 open an SCSI bus 5 and when the phase is not the message out phase, dummy data are exchanged between the target devices 3 and 4 by the initiators 1 and 2. Then, the change of the phase into a message phase or a bus free phase is waited.

Title: Semiconductor direct-current switching circuit
Inventor: TOMITA SHIGEO
IPC: H03K17/732
Filed: 1978-12-27
Abstract: PURPOSE:To prevent a control input signal circuit from malfunctioning effectively by providing this control input signal circuit with a voltage converter circuit which boosts a control input signal voltage up to a constant voltage and a malfunction preventive circuit which forms the gate-cathode short circuit when a thyristor is OFF. CONSTITUTION:Control input signal voltage V1 inputted between input terminals 1 and 2 is boosted by voltage converter circuit 5 up to constant voltage V2. This voltage V2 turns thyristor 8 ON to ignite gate turn-off thyristor CTO14, and consequently CTO14 is ON while thyristor 8 stays ON. When input control signal voltage V1 disappears, thyristor 8 is ignited to place CTO14 in an OFF state and thyristor 8 remains OFF until a following ON signal is applied between input terminals 1 and 2. Therefore, switching operation is possible by the control input signal voltage and malfunction due to a DC circuit can be prevented effectively.

Title: Ultrasonic motor driving gear
Inventor: NOMURA HIROYOSHI
IPC: H01L41/04
Filed: 1987-06-26
Abstract: PURPOSE:To obtain the stable driving gear of high efficiency, by using AC voltage sweeping periodically from a driving-frequency-higher section to a section lower in driving frequency. CONSTITUTION:By the one side detection output of a mechanical arm current detecting circuit 8, through a peak holder 9, the amplitude value of mechanical arm current is detected, and the input to a micro-computer 1 from an A/D converter 10 is provided. Then, the mechanical arm current is detected, and the value Im of the current and the value Imo of the mechanical arm current driving frequency just before the value Im are compared with each other. When the Im is greater than the Imo, then a specified frequency value is subtracted from the driving frequency, and when the Im is less than the Imo, then specified frequency is added to the driving frequency. In other words, frequency is changed and swept from its higher section to its lower section till the mechanical arm current is reduced: when the driving frequency comes to resonance frequency and the mechanical arm current is suddenly reduced, then the frequency is swept from its higher section to its lower section in the same manner after the specified frequency is added to, and so as a result, a device is driven by the only frequency approximate to the resonance frequency, and high efficiency is obtained.
